Y., ASSIGNOR TO MCMILLAN BOOK COM- PAN Y, OFSYRACUSE, NEVJ YORK, A CORPORATION OF NEW YORK LEAF FLIPPER Originalapplication filed. October 13, 1928, Serial No. 312,240. Div iz1ed andthis application filed T September 11, 1929.

This invention relates to a new andimproved leaf flipper for use withloose leaf binders and is particularly well adapted to be used withloose leaf binders of the split ring or arcuate prong type, and is adivision of my co-pending application Serial No. 812,24l0, filed Oct.13, 1928.

When binders of this type are open and it is desired to close them bymoving the covers towards each other such movement of the covers willmove the sheets in the binder around the binder rings or prongs. Thesheets ofsuch binder are held in position by virtue of the fact thatthey are provided with apertures along a longitudinal edge in which therings or prongs are positioned, such apertures usually being circular inshape and of a diameter slightly larger than the ring or prong whichextends through them.

In binders of this type the rings or prongs are usually positioned on abackmember to the outside edges of which are hinged the covers of thebinder with the result that the portions of the sheets with which therings or prongs are engaged are positioned between the hinges of thecovers so that'when the covers are raised for the purpose of closing thehinder. the outer edges of-the sheets will be raisedabove the inneredges of the sheets with the result that the rings'or prongs will assumean oblique position with reference to the apertures in the sheets whichwill cause the sheets to bind on the rings or prongs to a certain degreeand resist movement around such rings or prongs. The sheets usually usedwith this type of binder being th n there is considerable possibility ofinjury to the sheets when they are thus forced along the rings orprongs, which isparticularly true of the sheets which are ad acent tothe covers.

In order to permit the movement of-the sheets along the rings orprongsit is desirable to provide a means which will provide a suport for theleaves during such movement and which will also hold the 19c ves msuch aposition with reference to the rings or, prongs ,that there will be notendency of the leaves to bind on the prongs during their movement, andthe main obj ect'of my invention is to provide a device which may beinterposed be- Serial No. 391,926.

tween the leaves of a binder and the covers of the binder to act as asupport and guiding means for the leaves while tl e binder is beingclosed.

Other objects and advantages relate to the size, shape and arrangementof parts, all as will more fully appear from the following do scriptiontaken in connection with the accompanying drawings, in which:

Figure 1 is a perspective View of the preferred form of my device.

Figure 2 is a top plan view, partially broken away and partially insection, showing two of my devices in position on a binder with a leafin position on one of such devices.

Figure 3 is a section on line 3-3 of Figure 2.

For the purpose of explaining the constructionand operation'of my deviceI have here shown one type of a split-ring binder 1 comprising a backmember 2 and covers 3 and 4: connected to back member 2 by flexiblehinges 5 and 6 respectively. A curved spring plate 7 is afiixed to theupper surface of back member 2 by rivets or other convenient means, notshown. Spring plate 7 has its opposite longitudinal edges return-bent toform channels 8 and 9. A toggle plate 10 having aifixed thereto aplurality, in this case shown as five, of half-rings 11 is positioned onback member 2 with one longitudinal edge in channel 9 of spring plate 7A second togg-le plate 12 having a'liixed thereto a plurality, in thiscase shown as five,of halfrings 13 is similarly positioned on backmember 2 with its outer longitudinal edge in channels '8 of spring plate7. A plurality of doubleheaded buttons 14, one only being shown, are

positioned between the inner longitudinal.

edges of toggle plates 10 and 12 with such edges between the heads ofthe buttons 14.

The combined width of toggle plates 10 and this position by the pressureof spring plate 7. When it is desired to raise the inner longitudinaledges of toggle plates 10 and 12 above the outer longitudinal edges ofsuch plates to separate half-rings 11 and 13 such movement is permittedby the resiliency of spring plate 7, and when such movement has beencompleted the parts will be yieldingly held in that position by thepressure of spring plate 7. The movement downwardly of the innerlongitudinal edges of toggle plates 10 and 12 and the correspondingupward movement is limited by the buttons 14 which permit only a limitedmovement of the edges of toggle plates 10 and 12 between the heads ofbuttons 14.

A curved cover plate 15 is positioned above toggle plates 10 and 12.Cover plate 15 has its longitudinal edges returnbent so that it may besprung over the longitudinal edges of spring plate 7 and be heldsecurely in that position. Cover plate 15 is provided with slots 16 and17 to permit the movement therethrough of half-rings 11 and 13 as thesame are closed and opened. The upper end of half-ring 11 is V-shape inform so that it may enter a V-shaped slot in the upper end of half-ring13 when the two rings are brought together, half-rings 11 and 13 beingsopositionedon toggle plates 10 and 12 respectively that half-ring 11 willregister with opposing half-ring 13.

The preferred form of my leaf-supporting device, as perhaps may best beseen from 'Fi ure 1, consists of a substantially rectangular-shaped body18 made of metal or fibre or other sufficiently stiff material. Body 18is provided with a plurality, in this case shown as five, of ovalapertures 19 so positioned that they will register with eitherhalf-rings 11 or half-rings 13 when the body 18 is placed in position inthe binder. Body 18 is formed with an approximately V-shaped upwardlybent rib 20 positioned between apertures 19 and the edge of body 18. Rib20 is so formed asto provide a vertical ledge or stop 21 adjacentapertures 19 and in spaced relation thereto.

Although not essential for the functioning of my device, I here show inthe edge of body 18, adjacent rib 20, a plurality of notches 22 inalinement with apertures 19, which notches 22 come into registrationwith prongs 11 or 13 when the binder is being closed.

In use it isdesirable to use two of my deyices, onecooperating with eachof the covers ,Qf the binder, and I have here shown in Figure 3 one ofmy-devices in position on cover 3 with no leaves thereon and asecond oneof myfdevices in position on cover 4 with a plurality of leaves 23 inposition on the device.

The leaves 23 are provided with apertures 24 so positioned as toregister with halfrings 11 or 13, and for a purpose hereinafter to bedescribed it is desirable to have the distance between the centers ofapertures 21 and the longitudinal edge of the sheet greater than thedistance between ledge 21 and the center of oval apertures 19.

lVhen the parts are in the position shown in Figure 3 and cover 3 israised for the purpose of closing the binder it will raise with it theouter edge of body 18 which will cause the outer end of aperture 19 tocontact with half-ring 13 and ride upwardly thereon, the inner end ofbody 18 moving outwardly along the upper surface of cover plate 15 toguide body 18 in its upward movement.

hen cover 4 is raised in a similar manner the body 18 will move upwardlyin the same way as the body 18 moved upwardly on cover 3 as justdescribed, and in doing so it will carry upward with it the sheets 23which are positioned on its upper surface.

The relation of parts is such that the inner longitudinal edges ofsheets 23 will rest against the ledge 21 on body 18, and inasmuch as thedistance, as just described, be-

tween the inner longitudinal edges of sheets and the centers ofapertures 24: is greater than the distance between ledge 21 and thecenters of apertures 19, the apertures 24 in sheets 23 wi 1' be held insuch a position that the outer edges of apertures 24 will be in spacedrelation to the outer surfaces of halfrings 11 and there will be notendency for apertures 24 to bind on half-rings 11.

In Figure 3 I have shown inheavy lines the binder in the open positionand in dotted lines the binder in the partially closed position.

It will be understood that the material from which my device is made maybe varied as desired and it will also be understood that the size,number and relative position of the apertures 19 and the notches 22 maybe varied as inlay the height and length of the sto 21 in or er that mydevice may be ada te for use with different types of bin er, foralthough I have shown and described a specific structure and form ofpart as an exemplification of an embodiment of my invention, I do notdesire to restrict myself to the exact size, shape or relation of artsas various changes may be made wit in the scope of the appended claims.

I claim: i 1. In a device of the class described, a plate having aplurality of spaced apertures adjacent one edge and a vertically andlongitudinally extending stop between the apertures and the edge of theplate and in spaced relation to the apertures;

2. In a? device of the class described, a plate having a plurality ofspaced oval a'pertures adjacent one ed e' and a vertically andlongitudinally extending between the apertures and theedge of the plateand in spaced relation to the apertures.

3. In a device of the class described, a plate having a plurality ofspaced apertures adjacent one edge, and a portion of the plateintermediate the apertures and the edge of the plate being bent upwardlyto form a vertically and longitudinally extending stop positioned inspaced relation to the apertures.

&. In a device of the class described, a plate having a plurality ofspaced oval apertures adjacent one edge, and a portion of the plateintermediate the apertures and the edge of the plate being bent upwardlyto form a vertically and longitudinally extending stop positioned inspaced relation to the apertures. 5. In a device of the class described,a

plate having a plurality of spaced apertures adjacent one edge, and avertically and longitudinally extending stop in spaced relation to andpositioned between the apertures and the edge of the plate.

6. In a device of the class described, a plate having a plurality ofspaced oval apertures adjacent one edge, and a vertically andlongitudinally extending stop in spaced relation to and positionedbetween the apertures and the edge of the plate.
